EMBROIDERY-HOOP HOLDER.

Application filed August 3, 1927. Serial No. 210,283.

My invention relates to improvements in embroidery hoop holders and has for its principal object to provide a better fastening means to secure the holder to a table or the like, while other objects of the improvements pertain to simplifying the holder structure both from the standpoint of production and use.

I have been granted Patent No. 1,631,355 on June 7, 1927, for an embroidery hoop holder and the present invention is an improvement thereon.

I attain these and similar objects of my improvement with the mechanism illustrated in the accompanying sheet of drawings forming a part of this specification in which Figure 1 is a side elevation of my embroid ery hoop holder clamped to a support and clamping an assembled pair of embroidery hoops therein the latter being shown as having the major portion thereof broken away; Fig. 2 is a front elevation of Fig. 1 with the table support and hoops not shown; Fig. 3 is a perspective view of the loose jaw of the hoop clamp, and Fig. 4 is a perspective view of the loose jaw of the table clamp.

Similar characters refer to similar parts throughout.

More particularly: Frame upright 5 is bent rearward at its lower end to form fixed jaw 10 of the table clamp, and said upright is bent slightly forward at its upper end to form the fixed jaw a of the hoop clamp.

Near the lower end of the upright is medial longitudinal slot 9. In fixed jaw 10 near its juncture with the upright is a medial bolt hole through which is extended clamping bolt 22. Near the upper bend in the upright is medial transverse slot 8 and above and near this slot is a medial bolt hole through which is extended clamping bolt15.

Loose jaw 6 is bent forward at its lower end to bear on the upright and has medial tongue 14.- protruding therefrom to engage in slot 8. It also has hole 12 projected through it to align with said bolt hole near slot 8 when said loose jaw is in operative position and through these aligned holes is extended clamping bolt 15 having wing nut 16 thereon to make 'said hoop clamp effective. The ends of both of jaws a and 6 are preferably curved to conform to the shape of hoops B, B, which are shown in Fig. 1 as retaining fabric 0 and as clamped between jawsa' and 6.

Loose jaw 7 of the table clamp has trans 7 To properly engage jaw 7 with the up-' right it is passed from the front thereof rear end foremost through slot 9 till notches 18 register with said upright when the jaw is turned over through 90 to bring it horizontal with its loop 20. downward and bearing on the front side of the upright.

This is the operative position of jaw 7 shown in Figs. 1 and 2'and it may be noted that said jaw is free to move up and down in slot 9 and is substantially parallel with fixed jaw 10 from which relation it can not be diverged because of loop 20 which serves to stop the upward swing of said jaw around a transverse axis through bridge 19.

Hole 12 is projected through loose jaw 7 to be in line with said bolt hole in fixed jaw 10 and through these aligned holes is extended clamp bolt 22 which is made effective by wing nut 23 on said bolt.

The opposite surfaces of jaws 7 and 10 are preferably covered with felt pads 17 and 11, respectively, and in Fig. 1 the lower clamp is shown as engaged with support A which may be a table top, shelf, bracket or like supporting structure By preference, clamp bolts 15 and 22 have fiat-round heads and their threaded bodies closely approach said heads. This kind of stock bolt usually has no square shank, for which reason holes 12 and 21 may be round.-

.To prevent the bolts 12 from turning in these holes I prefer to weld the said heads to the loose jaws. For this reason loose jaw 7 can not be removed through slot 9 and bolt 22 should not be welded thereto till the aw is in place in the upright.

It is now easily seen that when constructed as illustrated and described the table clamp jaws 7 and 10 are maintained in substantially parallel relation even under the force of clamping bolt 22, and the rear ends of these jaws firmly clamp on the support A as well as those parts of said jaws near said clamping bolt.

As stated, this is the principal object of this invention.

Having thus disclosed my invention, What I claim as new therein and desire to secure by Letters Patent is,-

1. A clamping device of the kind described consisting of a frame member having a vertical longitudinal slot therein, a rearwardly extending jaw rigidly fastened to the lower end of said frame member, a loose jaw theforward end of which is downwardly folded forming a loop having transverse notches in the edges thereof rearwardly of said loop with a bridge between the bottoms of said notches engaged with said frame member in said slot said notches engaging said frame member whereby the lower end of said loop bears on the front of said frame member when said loose jaw is parallel with said fixedjaw behind said frame member and is vertically movable through parallel positions in said frame member slot, and -a clamping bolt extended through aligned holes in said jaws.

2. A holder of the character described consisting of an upright frame member having a longitudinal slot near its lower end, a hoop clamp on the upper end of said upright member, a rearwardly extended fixed jaw integral with the lowerend of said upright member, a loose jaw operatively parallel with said fixed jaw engaged in said slotfor vertical movements therein, a loop integral with the front end ofsaid loose jaw folded downward to bear on the front of said upright member when said jaws are parallel, and a clamping bolt extended through aligned holes in said jaws proximate said upright member.
